General procedure: In a typical experiment Pd(OAc)2 (5.6mg, 0.025mmol), triphenylphosphine (13.2mg, 0.05mmol), iodoalkene (1-4) or iodoarene (5-19) (1mmol) were dissolved in DMF (10mL) under argon in a three-necked flask equipped with a reflux condenser and a balloon on the top. Aminotriazole nucleophile (a, b or c) (1.2mmol) and triethylamine (0.5mL) were added. The atmosphere was changed to carbon monoxide. (Caution: High pressure carbon monoxide should only be used with adequate ventilation (hood) using CO sensors as well.) The reaction was conducted for the given reaction time upon stirring at 70C. The mixture was then concentrated and evaporated to dryness. Toluene (15mL) was added to the residue, the precipitate (product) was filtered, washed with water on the filter and dried.
